Type: Concrete screw Definition: Concrete screw, also called anchor screw or concrete bolt, are designed for quick, safe, secure fastening for a variety of jobs in concrete, cement, brick, cinder block and masonry. Description: Concrete screw is an externally threaded, hardened screw with a double lead, consisting of alternating raised and lowered threads with notches cut into the threads, and a diamond-shaped, nail type point. Application: Concrete screws eliminate the need for an anchor when used in light and medium duty applications. When used in concrete, concrete screws can be removed and re-driven into the same hole. Concrete anchor screws provide self-threading action and maximum holding power for anchoring the following to masonry: electrical junction boxes, wooden beams, plywood, exterior insulation, metal flashing, expansion joints, duct straps, gutters, fixtures, and thresholds. These screws are available in two different head styles: flat head and hex head. Flat head screws have a phillips drive style, while the hex head can be a slotted or unslotted indented hex head style. Others: Special carbide bits are recommended for driving the screws into masonry. Feel Free to contact us if you have any questions. Feel Free to contact us if you have any questions.
